trouble shooting

The troubles you describe could be more than one. It is hard to troubleshoot one without seeing it function. The feeling that the trigger is trying to come forward when the hammer is falling would send me looking at the main spring and the mainspring tension. It sounds like someone has changed the main spring and also has the wrong tension on the new one. Some Smith & Wessons are picky about their mainspring. In an attempt to get a better trigger pull some people replace the mainspring and also attempt to loosen the tension screw in the grip frame. You are better served with a standard mainspring and good tension on the screw than to try to lesson the trigger pull with a lighter spring. Those issues can be addressed by going to a lighter trigger return spring and polishing its housing inside and out. I am only guessing as I can not see the gun. Good luck.
